“…Furthermore, although trust and security protocols can be used to ensure that the vehicles cooperate and are accountable for the information that they share (e.g., [18], [19], [20], [21], [22]), we were also interested in identifying what is the impact of misbehaving nodes on the traffic conditions. In our scenario, misbehaving nodes are nodes that intentionally spread wrong information about a pre-agreed selection of road segments.…”

Abstract-Road congestion results in a huge waste of time and productivity for millions of people. A possible way to deal with this problem is to have transportation authorities distribute traffic information to drivers, which in turn can decide (or be aided by a navigator) to route around congested areas. Such traffic information can be gathered by relying on static sensors placed at specific road locations (e.g., induction loops, video cameras) or by having single vehicles report their location, speed and travel time. While the former approach has been widely exploited, the latter has seen birth only more recently, and, consequently, its potential is less understood. For this reason, in this paper we study a realistic test case that allows to evaluate the effectiveness of such a solution. As part of this process: a) we designed a system that allows vehicles to crowd-source traffic information in an Ad-Hoc manner, allowing them to dynamically reroute based on individually collected traffic information, b) we implemented a realistic network-mobility simulator that allowed us to evaluate such a model, and c) the main focus of this paper: we performed a case study that evaluates whether such a decentralized system can help drivers to minimize trip times. This study is based on traffic survey data from Portland, Oregon and our results indicate that such navigation systems can indeed greatly improve traffic flow. Finally, to test the feasibility of our approach we implemented our system and run some real experiments at UCLA's C-Vet test-bed.

“…This equates to about 43,800 pseudonyms per year for an average of two hours of driving per day [21]. Haas, Hu, and Laberteaux in [11] recommend changing pseudonyms every 10 minutes, and driving 15 hours per week. This equates to 4,660 pseudonyms per year, but they recommend storing five years of pseudonyms for a total of about 25,000 pseudonyms per OBU.…”

Abstract. Certificate revocation is a challenging task, especially in mobile network environments such as vehicular ad Hoc networks (VANETs). According to the IEEE 1609.2 security standard for VANETs, public key infrastructure (PKI) will provide this functionality by means of certificate revocation lists (CRLs). When a certificate authority (CA) needs to revoke a certificate, it globally distributes CRLs. Transmitting these lists pose a problem as they require high update frequencies and a lot of bandwidth. In this article, we propose BECSI, a Bandwidth Efficient Certificate Status Information mechanism to efficiently distribute certificate status information (CSI) in VANETs. By means of Merkle hash trees (MHT), BECSI allows to retrieve authenticated CSI not only from the infrastructure but also from vehicles acting as mobile repositories. Since these MHTs are significantly smaller than the CRLs, BECSI reduces the load on the CSI repositories and improves the response time for the vehicles. Additionally, BECSI improves the freshness of the CSI by combining the use of delta-CRLs with MHTs. Thus, vehicles that have cached the most current CRL can download delta-CRLs to have a complete list of revoked certificates. Once a vehicle has the whole list of revoked certificates, it can act as mobile repository.

Vehicular Ad hoc Network (VANET) is a promising emerging technology that enables road safety, traffic management, and passengers and drivers comfort applications. Many applications require multi-hop routing; position-based routing (PBR) is a well-recognized routing paradigm that performs well in the vehicular context to enable these applications.However, there are many security challenges and various routing attacks which may prevent the deployment of PBR protocols.In this study, we propose a novel security scheme called ESPR to secure PBR protocols in VANETs. ESPR considers both digital signature and keyed Hash Message Authentication Code (HMAC) to meet the unique requirements of PBR. In ESPR, all legitimate members share a secret key. ESPR scheme applies a novel probabilistic key distribution to allow unrevoked members to update the shared secret key. Furthermore, it defines a set of plausibility checks that enables network members to detect and avoid PBR attacks autonomously. By conducting security analysis and performance evaluation, ESPR scheme demonstrated to outperform its counterparts in terms of communication overhead and delay while achieving robust and secure operation.iii Acknowledgements All praises are due to Allah for giving me the ability to write this work.
